Hello fellow Oilers, my trusty Frontier was totaled in a hail storm up here in Michigan. It's replacement is a rust free, 200k mile 1990 Chevy C1500. It has a very good running 350 TBI. I recently learned that it's a flat tappet engine...I thought all small blocks were roller lifters after 1987. Oh well. Being a stock engine with low spring pressures, are they sensitive to Zinc in oil like hi-po builds? My first thought was Valvoline MaxLife 10W-30. Is it adequate l, or should I add zinc additive/look for another oil? Please share your stories/recommendations. I have one week before shes on the road.
